ICP Gas Valve Support Bracket for RGS121HTAB0AAAA — OEM 1178238 | Ships Today

Overview

This OEM gas valve support bracket, part number 1178238, is the direct-fit mounting bracket for the gas valve on the ICP / Heil / Tempstar RGS121HTAB0AAAA furnace. The bracket holds the gas valve in its correct position and orientation relative to the manifold and burners, preventing strain on the gas piping connections and isolating the valve from vibration. A bent, corroded, or missing bracket allows the gas valve to sag or move, which can stress the inlet and outlet pipe joints, misalign the manifold, and create the conditions for a gas leak or improper burner firing. Replacing a damaged bracket restores proper valve alignment and a safe, secure gas train.

Specifications

Compatibility

Designed as an exact OEM replacement for the ICP / Heil / Tempstar / Comfortmaker RGS121HTAB0AAAA furnace gas valve assembly. The bracket matches the factory mounting hole pattern and valve standoff geometry for this platform. Confirm your model and serial tag before ordering.

Installation Guide

1. Safety First — Shut off the gas supply at the manual shutoff, disconnect electrical power, and verify zero voltage with a multimeter.
2. Access — Remove the service panel to expose the gas valve and manifold.
3. Document — Photograph the valve orientation, bracket position, and pipe routing before disconnecting anything.
4. Remove — Support the gas valve, then remove the fasteners securing the old bracket and lift it out.
5. Install — Position the new bracket, fasten it to the chassis, and re-secure the gas valve at the correct height and angle.
6. Test — Restore gas and power, leak-check all gas joints with soap solution, and confirm normal burner ignition and operation.
